After you prepare the Logging Node cluster for upgrade, use these procedures to upgrade the Logging Nodes in your cluster.
Before upgrading the F5® BIG-IQ® Centralized Management Logging Node, perform these tasks.
|Re-activate the BIG-IQ system license.||You must do this on both the active and the secondary BIG-IQ if they are running in an HA pair. For specific instructions about how to reactivate a license, refer to the F5® BIG-IQ® Central Management: Licensing and Initial Setup guide.|
|Decide which disk volume you want to install the upgrade on. You must have at least two volumes to upgrade BIG-IQ.||If you are running BIG-IQ Virtual Edition and you don't have two volumes, refer to: K1740617406: Using the tmsh utility to create a new software volume for installing a new image or hotfix on the BIG-IQ system at: support.f5.com/csp/article/K17406|

You upload the BIG-IQ version 5.2 software image to your Logging Node to make it available for this upgrade.
The default size of the /var file system in a newly installed Logging Node is 10 GB. That may be insufficient to store logging data. Extending this file system to a larger size is explained in SOL 17406. Because upgrading a Logging Node installation requires at least two volumes, you must ensure that both volumes can have their /var file system extended to the same size, or upgrades may fail. If you are running BIG-IQ Virtual Edition and don't have two volumes, refer to: SOL17406: Using the tmsh utility to create a new software volume for installing a new image or hotfix on the BIG-IQ system at support.f5.com/kb/en-us/solutions/public/17000/400/sol17406.htmlBefore upgrading Logging Node, you must have downloaded the BIG-IQ version 5.2 .iso image from the F5 downloads site.
The upgrade process involves installing the new version of the software, booting into that new version, and reviewing the settings on the setup screens.
After you upgrade to BIG-IQ® version 5.2, you will notice a few differences in performance.
